Does the Revolar app work without a Revolar wearable?

You will need to purchase a Revolar wearable in order to download and use the Revolar app.

However, once you have the Revolar app you can use it to send alerts the same way you use your wearable. Simply open the app and tap the button on the home screen two times to send a Yellow Alert, or three times or more to send a Red Alert.
